ATTORNEY` Patented Mar. 4, 1941 UNITED STATES PATENT OFFICE 2 Claims.

hem in the latter, which may be employed in connection with any type ofwindow shade, which may be secured or removed without damage to thewindow shade, even by unskilled persons, and whereby the reversal of thewindow shade may be conveniently eected,

Another object of my invention is to provide a device of the abovedescribed character which ymay be readily attached to window shadesalready in use without modifying the latter and to window shades inwhich the hem portion has been severed or partially severed therefrom.

A further object of my invention is to provide 20, a device of the abovedescribed character which is simple in construction, durable in use,efficient in operation and economical in manufacture.

Other objects and advantages will be apparent from the followingdescription, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designatelike parts throughout the several views:

Figure l is an elevation of a window shade illustrating my invention asapplied thereto.

Figure 2 is a detail sectional View, on an enlarged scale, taken on theline 2--2 of Figure 1 and illustrating my invention in attachedcondition to a shade. v

Figure 3 is a View similar to Figure 2 butillustrating my invention incondition for removal from or attachment to a shade.

In practicing my invention, as illustrated in the drawing, I provide awindow shade 5, the

I o upper end (not shown) being attached to a shade roller 6. The lowerend section 'I of the shade has attached thereto my improved form ofwindow shade attachment 8, the latter comprising an elongated relativelythin resilient body inflected between its side edges to dene adjacentlydisposed side walls 9 and I0. The side wall 9 is formed with alongitudinally extending upper edge section II bent upon itself as at I2and terminating ina beaded portion I3 disposed away from its wall 9, Theside wall ID is formed with a longitudinally extending intermediatesection I4 having a portion I5 bent upon itself and termnating in a loopI6 fashioned with a lengthu wise extending edge section I'I disposed inproximity to the section II for clamping therebetween a portion of thelower end section of the shade 5. The loop I 6 denes a lengthwiseextending channel I8 in which the portion I3 extends a suicient distanceto coact with the wall of the l channel to cohibitv movement of thewalls 9 and I0 in a direction away from each other. When the portion I3is thus disposed within the channel I8 the intermediate section I4coacts with the wall 9 to clamp an adjacent portion of the shade l0 5therebetween. The lower side edge of the body has swiveled thereto aneye I9 to which is attached a shade raising and lowering cord 20 wherebysaid shade may be operated.

From the foregoing it will be apparent that l5 when the walls 9 and I0are urged in a direction away from each other, the lower edge section ofthe shade 5 may be inserted therebetween as clearly illustrated inFigure 3 of the drawing. When the lower edge section of the shade isthus .l0 inserted between the walls 9 and I 0, said walls are moved inadirection towards each other causing the beaded portion I3 to snap intothe channel I8 and elTect clamping of adjacent portions of the shadebetween the sections I I and u Il and the section I4 and wall 9subjacent the section II respectively, thereby providing an attachmentby which the lower non-selvedge edge of the shade is protected fromraveling and for operating the shade.

It is obvious that the invention is not coniined to the herein describeduse therefor as it may be utilized for any purpose to which it isadaptable.

It is therefore to be understood that the invention isnot limited to thespecific construction 85 as illustrated and described, as the same isonly illustrative of the principles of operation, which are capable ofextended application in advance forms, and that the inventioncomprehends all construction within the Ascope of the appended o claims.

What I claim is:

1. In a device of the character described, comprising an elongatedrelatively thin resilient body portion having its upper edge bentinwardly Aand 5 downwardly and turned upwardly to form a beaded portion,the lower edge of the body portion bent upwardly to a point opposite tothe beaded portion of the downwardly turned portion, the upper edgethereof turned downwardly and upwardly and ared outwardly, whereby whena piece of fabric is placed between the lower edge of the downwardlybent portion and the upper edge of the upwardly bent portion the fab- Mric is clamped at three distinct points when the loop portions aresnapped together.

2. In a device of the character described comprising an elongatedrelatively thin body portion having its upper edge bent inwardly anddownwardly, the lower edge of the body portion bent upwardly to a pointopposite the lower edge of the downwardly turned, portion, the upperedge thereof turned downwardly and upwardly and flared outwardly,whereby when a. piece of fabric is placed between the lower edge of thedownwardly bent portion and the upper edge of the upwardly bent portion,the fabric is clamped at three distinct points when the loo-p portionsare snapped together.
